' r This invention relates to a water heater'and more particularly to awater heater in which 011 is used as the fuel. I

It is the general object of the invention to provide a new and improvedhot water heater.

Among the objects of the present invention are: to provide a novel andimproved heater of the character referred-to; to provide a novelarrangement of oil burner and associated parts for heaters for heatingwater and the like; to provide a novel mounting for the oil burning pot;and the provision of a novel combination of an air inlet opening andplunger rod assembly.

Other objects and advantages will become readily apparent from thefollowing detailed description taken in connectionwith the accompanyingdrawings, in which:

Fig. 1 is a vertical longitudinal centralsection through a heaterembodying our invention, parts being shown in side elevation forclearness.

Fig. 2 is a to plan view of Fig. 1.

Fig. 3 is a fragmentary vertical central section through the lowerportion of our heater and showing the structure formounting the oilburnerpot therein.-

Fig. 4 is a transverse section on the line 4--'4 of Fig. 3.

Our invention further resides in the combination, construction andarrangement of parts illustrated in the accompanying drawings, and whilewe have shown therein a preferred'embodiment we wish it understood thatthesame is susceptible of modification and change without departing fromthe spirit and scope ofthe appended claims.

Referring more in detail tothe drawings our improved heater comprises ametal outer casing I mounted at the bottom upon a base 2 having legs 3,and having fixed to the top thereof a top late 4. Spaced inwardly adistance from the outer casing I is an inner metal casing 5 which islikewise mounted upon base 2 and at'its upper end is provided with thetop plate 6 likewise spaced from the outside top plate 4. The spacebetweenthe outer and inner casings I and 5, and between the top plates 4and 6 is filled with any suitable insulating material 'I as desired.Extending through registering openings in the top plates 4 and 6 and theadjacent portions-of the insulating material I is a tube 8 through whichpasses the gaseous. products of combustion from the oil burner pot latermore fully described. Any suitable means (not shown) may be applied atthe top of tube 8 for conducting the gasesof combustion from the tube 8to a flue leadin o 7 Claims. (Cl. 12694) thereof a curved bottom plateI2 having a cen-.

tendingto the lower portion of the inside of the tank is a fill pipe IIthrough which the water or other liquid to be heated is introduced intothetank. Through nipple I0 may be passed any suitable pipe or tube toconduct the heated water from the inside of-the tank to any desiredplace of use. I v I As seen in Figs. 1 and 3 there isprovided within thetank a distance above the bottom end tral opening I3 through whichextends the bottom end of tube 8, which tube is welded or otherwisesecured in watertight relation to bottom plate I2, and which plate mayalso be welded or otherwise secured in watertight relation to theinterior of the inner casing 5. As seen in Fig. 1

the bottom end I4 of tube 8 extends a slight distance below the bottomplate I2. Secured at diametrically opposite points to the lower face ofbottom plate I2 are bracket members I5 each provided in its vertical webwith an opening I6 through which are hooked the curved ends I! of thehanger rods I8, which at their bottom ends are formed with threads I9threaded over which are wing nuts 20, above which wing nuts are washers2|. Support-bar 22 is provided at its opposite ends with openings 23,one of which for convenience in mounting is in the form of an open endedslot, through which openings extend the hanger rods I8 so that the endsof the support-bar, after the parts are assembled, rest upon the washers2|. As will be understood the support-bar 22 is slipped over the rods I8after which the washers and wing nuts are applied. As seen in Fig. 3this structure constitutes a hanger or support within which the oilburner pot is mounted.

Support-bar 22 at its middle portion is formed with an upwardlyextending rib 24. Positioned directly above support-bar 22 is a plate 25formed at its mid portion with longitudinally spaced depending ribs 26,within the space between which is fulcrumed the rib 24 of thesupport-bar. The depth of ribs 26 is less than the height of rib 24 soas to ermit a rocking action of the plate 25, as may be required toproperly position the parts during assembling. Positioned in spacedrelation around the outer portion of the plate 25 are three equallyspaced upstanding ribs 28, each tom' corner edge of the burner pot so asto position the burner pot with relation to the heatplate and hold itthereon. The oil burner pct 30, which is formed in it side walls withair holes 3|, is provided at its top with a top plate 32 having anannular groove 33 formed therein to be seated against the bottom endedge of the tube 8., Formed centrally in the top plate 32 is an opening34 having communication .on its lower side with the [interior of theburner pot and having communication on its upper side with the interiorof the tube 8, so that the not combustion gases may passfromthe'interi'orof the pot to the interior of the tube 8. Thecombustion of these gases will be substantially :com-. pleted withintube 8 to heat the mvateror :other liquid within the tank.

In assembling the burner ;pt .in position the hanger rods 18 are firstinserted by means of their hooks H in the brackets l5, which bra-cketsare each welded or otherwise secured by the angular leg 35 to thelowerface-of the bottomplate 1.2. The .support-bar22 will thenbe positionedupon these hanger rods through the medium of openings ZB and thewashersZl applied over these rods below the supportbar. The wing. nutswill then be threaded onto the lower'end of these .hanger rods, theheat-plate placed upon the support-bar with rib 24 in the space betweenthe shorter ribs 26, and the burner ,pot 30 positioned within the curvedrecesses .29 of ribs .218. The pot top plate 32 is then placed on theburner pot with the annular flange .tt positi-oned within the upper edgeof the burner pot walls, and the bottom and edge of the tube .8 insertedin groove 33,. aft.er

which the nuts will be tightened upon the g hanger rods +8 to bringthese partsinto secured and tightened position. It will be understoodthat-as these parts are being clamped together "as described, the platemay tilt on the Support-bar as may berequired to make 'a tight jointbetween the bottom of tube sBand the top plate 3.2 and bring all ofthese parts in desiredassembled and tightened relationship. As theclamping of these parts proceeds one or the other of the nuts .20 unaybe advanced faster or slower. than the other so as to afiord a properseating of the various parts, any adjustment being provided for by thetilting .of the plate as described above.

Extending through the wall of the pot '30 .at the bottom thereof andprojecting outwardly therefrom .is a ,plunger rodassembly .31 the rod'38 of which-extends through .the'opening Q39 in *the inspection-doorAll, .there being provided a handles .on theouter-end of the rod outsideof the inspection door llLso-as to enable manipula tion of the-rod tocontrol entry .ofoil to the interior of the pot as desired. As noted in.Fig. .3 the opening .39 around rod 38 is of substantially greater sizethan the-size-of the rod and handle .so asstopermit the entryzof airthrough hole 39 to the interior of the space 42 inuthe tankbelow -'-thetank bottom l2, to aid combustion-of the oil "within the pot rand withinthe tube 8, .such air passing through openings 3| in the pot walls intothe interior :of the pot. As will-'beunderstood-a shallow layer ofoil-will'be' present inrthe bottom nof the'pot so as to provide a largeupper-surface of oil :for vaporization. JIhe pipe-T 4.3 .in the plungerrod .assembly will be'connected to any within the heater, thearrangement of parts between the burner pot and the tube 8 being suchthat maximum heat will be transmitted through the walls of the tube 8 tothe water inside of the tank. Also it will be understood that ouradjustable arrangement of parts for clamping the oil burner. pot inposition at the .bottom of the :combustion tubeis suchthat the plate,due to its tiltable connection with the support-bar will automaticallbring these parts into proper position with relation to each otherduring tighteningfof'the nuts 2!]. A drain cook 45 is provided near'thebottom of the tank to enable draining :of athe tan-kas desired. Any wellknown and suit- ;able :heatmegulating means may be used as de-.ssired.for:;regulating the temperature of the water in the tank.
